Jorgur's medieval RPG. Gad, I miss that server so damn much.
Also, the first time I hosted a server, where only one guy joined (I honestly think it was Buddy or someone), and I banned him for not saying hello when he joined.
This was in a Fort Wars server, where everything was green, and there was a crappy maze under the map. Oh, yeah, I just remembered. I didn't even have a minigame up in there, and I got mad at this other guy for not shooting guns and stuff (and banned him, being the noob I was).
